[PATCH 1/3] wireless: iwlwifi: use bool instead of int

[Christoph BÃhmwalder]

Change a usage of int in a boolean context to use the bool type instead, as it
makes the intent of the function clearer and helps clarify its semantics.

Also eliminate the if/else and just return the boolean result directly,
making the code more readable.
